I don't see why not, also your not cooling as much space but I don't know if it would matter much.
What I did was build a rear wall that has wheels on the bottom and I can open and close it, and my gold cart fits in with no problem.




this may not work for others but works for me.
I like the wall with a regular screen door than the screen that covers the back, when it's hot or cold I have insulation plugs I put in and can take out.
